If you're talking about userbase, I presume, Go should have less of a userbase than lisp.

People use lisp for something other than a programming discussion talking point?

The message board that you posted this to. Written in Arc which is a dialect of lisp.

Once again, downvotes are leaned on in lieu of wit.

So you mean they use it to create an application that allows them to... talk about lisp.

So, the correct answer here would've been that Viaweb--Graham's company that later became Yahoo! Store--was done in Common Lisp. I'm not really aware of any other example of Common Lisp in a real commercial setting other than Mirai (which I think is dead nowadays anyway).

Graham later made Arc, the language in which HN is written. To the best of my knowledge Arc's only major project is in fact Hacker News.

So, essentially, yes, you're correct.
